The Hermit Flower-beetle, Osmoderma eremicola (Os-mo* 
der'ma er-e-mic'o-la).—This is one of the 
larger of our Flower-beetles (Fig. 684). It 
is of a deep mahogany-brown color, nearly 
smooth, and highly polished. It is sup¬ 
posed that the larva lives on decaying 
wood in forest-trees. 
The Rough Flower-beetle, Osmoderma 
scabra (O. sca'bra), is closely allied to the 
preceding. It is not quite as large, meas¬ 
uring about one inch in length. It is 
purplish black, and the wing-covers are 
roughened with irregular, coarsely-punc¬ 
tured striae. It is nocturnal, concealing 
itself during the day in the crevices and hollows of trees. 
The larva lives in the decaying wood of apple and cherry, 
consuming the wood and inducing more rapid decay. 
The Bumble Flower-beetle, Euphoria inda (Eu-phoTi-a 
in'da).—The most common of our Flower-beetles, at least in 
the North, is a yellowish-brown one, with the 
wing-covers sprinkled all over with small, irregular 
black spots (Fig. 685). It is one of the first in¬ 
sects to appear in the spring. It flies near the 
surface of the ground with a loud humming 
sound, like that of a bumble-bee, for which it is 
often mistaken. During the summer months it is

middle of September. The adult is a general feeder occur¬ 
ring upon flowers, eating the pollen; upon corn-stalks and 
green corn in the milk, sucking the juices ; and upon peaches, 
grapes, and apples. Occasionally the ravages are very 
serious. 
The genus Euphoria represents well the form of the 
more typical Flower-beetles, which are distinguished by the 
margin of each wing-cover having a large wavy indentation 
near its base, which renders the side pieces of the meso-
